Since ancient times in Rus' they have been chopping wooden huts and tower. As construction technologies improved, other, more modern materials began to appear. However, to this day, a house made of timber is considered the most durable, environmentally friendly, reliable and strong. And it is not surprising that this is the material option that the owners choose during construction. country cottages. At the same time, many people prefer to build their house from rounded logs. Reviews from owners of ready-made cottages claim that this material is affordable and easy to use. Moreover, he has good quality and has a long service life.
Wooden houses
Today it is difficult to find a person who would not dream of living in his own cottage, built from environmentally friendly material. And this is only possible when using wood. Since ancient times, people have preferred to live in such houses. It was believed that all its rooms, saturated with woody spirit, had a beneficial effect on a person’s mood and well-being. And what can compare with the facade of such a house? The design of even the most modern buildings cannot be compared with it.
That is why houses built from rounded logs are very popular among consumers. And this despite the fact that their cost is twenty-five percent higher than the cost of frame buildings.
What is a rounded log?
What is this material? This is an ordinary log that was processed on a special machine with a rounding cutter system installed. Such mechanisms have been used for more than a century. However, initially the logs on them were processed for installation as
After the machine, the material takes on the form ideal cylinders having the same diameter and shape. The main advantage of such logs lies in their surface. After being processed on the machine, it becomes round and smooth. The material attracts many consumers, despite the fact that wood during processing loses a significant part of its most durable layer - sapwood.
For further use in construction, rounded logs are trimmed. They also create crown cups and grooves. Further mechanical processing of the surface of the material is also possible. So, some logs are left convex on both sides, while in others the part that will be located inside the built house is made flat. Next, the material is treated with various compounds to give it fire-fighting and antiseptic properties.
Types of rounded logs
The atmosphere in wooden house, will be remembered for a long time by those guests who live in a brick or panel cottage. She is characteristic clean air, which is soaked in essential oils.
Type of wood;
Log diameter;
Building area.
One-story houses made of rounded logs will cost less. They do not require delivery of a large number of floor beams.
Sometimes the first two crowns are made from the most expensive material - larch. This will protect houses made from rounded logs from rot and moisture. Prices for larch beams are quite high, which will immediately increase the cost of construction. In the estimate previously compiled by specialists, you will be able to familiarize yourself with the prices for the manufacture and installation of the building’s power kit. All this will also have a direct impact on the amount that will have to be paid for a rounded house. On average, with an area of about one hundred square meters you will need to shell out 1 million rubles.
Advantages of houses made of rounded logs
The main advantage of such cottages is the use of safe and environmentally friendly materials. Natural wood has a positive effect on human health, creating a favorable indoor microclimate. An important advantage of using rounded timber is that it does not contribute to the occurrence of an allergic reaction. Such a house will be completely safe even for small children.
According to reviews from the owners of wooden cottages, the advantage of such a building is significant savings on the purchase of climate control equipment. Unique properties trees allow you to support optimal values humidity levels, and also create coolness on the hottest days and provide warmth on cold days.
The tree species used to build a house are distinguished by their durability, reliability, increased strength and density. In addition, their natural beauty allows you not to waste additional funds on interior decoration premises.
When building a house standard project construction time is minimal. It is not difficult to assemble a log house from rounded logs. The construction process is greatly simplified by specially designed grooves and bowls in the material.
An important advantage of houses made of rounded logs is their lower cost compared, for example, to brick ones. That is why wooden construction is considered to be a budget option.
The advantage of houses made of rounded logs is their unsurpassed appearance. The design of such buildings will certainly evoke admiring glances from guests. In addition, houses made of rounded logs have excellent heat and sound insulation properties. This allows you to save on the purchase of insulating materials.
Disadvantages of houses made of rounded logs
The main disadvantages of such buildings include the construction period. Experts recommend taking a break from work for six months when building houses made of rounded logs. This time is necessary to complete the shrinkage process.
Besides, wooden buildings have low fire resistance. In order for the house to be as reliable as possible and have high level safety, the surface of rounded logs must be treated with special solutions.
Natural wood also needs protection from negative influence environment. For example, increased moisture will certainly lead to the appearance of fungi and mold, and will also cause the timber to rot. They destroy the tree and various pests. That is why the timber must be treated with special protective equipment.
In the form of wind, they can cause the logs to twist. This is also a disadvantage of such houses. Deformation of a rounded log can occur under the influence of precipitation and sun rays. To prevent these unpleasant phenomena, the material must be constantly monitored, covering the cracks special compounds. Otherwise, moisture will easily penetrate into the house through the gaps.
Wooden houses have been built quite actively lately. Quite often, chopped or rounded logs are used as the material. As a result we get beautiful log house, in which natural wood goes well with stone, glass and plastic frames.
Let's look at the main pros and cons of a log house to choose in favor this option was completely meaningful.
What is good about a log house - advantages
Let's start with the fact that wood has low thermal conductivity, so it is neither cold in winter nor hot in summer in a wooden house. For construction residential buildings I use wood coniferous species, deciduous ones are more suitable for a bath.
Another undeniable plus log houses– its relative cheapness. Let's start with just a box for which you need to buy windows and doors, lay floors and carry out other work. But for such an amount you definitely won’t be able to get even a similar result when using brick or foam block. In addition, a log house does not require a massive foundation.
If you built a house from a log frame, the benefits in the form of environmental friendliness and a comfortable microclimate will not keep you waiting. A wooden house “breathes” - has natural ventilation. Optimal, not regulated by anyone, humidity level in indoor feature, inherent in any wooden house. In such buildings, residents are less likely to get sick and practically do not complain about sudden fatigue or deterioration in well-being.
Let us note that wood is always beautiful. When producing any type of logs, the natural texture of the material is preserved, therefore, you no longer need additional finishing.
Another plus is the simplicity of the design. You can literally assemble a house made of logs with your own hands, if only you can find helpers to lift the logs and learn how to caulk the cracks between them. But in any case, almost anyone can understand the drawings and plans of a log house.
Recently, there has been a trend towards a constant decrease in orders for log houses. In order to somehow preserve the segment, unscrupulous competitors have created myths and negative reviews about a rounded log to compromise this view building material.
Our opinion is unchanged: any material has the right to exist, it is advisable to choose what corresponds to desires and capabilities. You should also take a responsible approach to choosing a development company, because the main characteristics of your future house made of rounded logs depend on them.
For you, we tried to dispel the following 5 myths:
See reviews of houses made of rounded logs
“Disadvantage” No. 1: Sapwood is a protective layer of wood
Adherents of hand-cutting say that the shortcomings and disadvantages of rounded logs are already visible in production, during which the sapwood, the most important protective layer, is removed.
In fact, sapwood is the younger layers of the tree; bast and bark are adjacent to them. Let's figure out what this “strongest and most important layer” is. If you believe Wikipedia, a resource that is the most important primary source of knowledge of our time, then Sapwood is lighter than inner part logs, and is characterized by less mechanical strength. It contains more water, since water is transported to the crown through it, and is less resistant to attacks by fungi and insects.
#BXSTYLE_0#
The same opinion is shared by the authors of the Bolshoi Soviet Encyclopedia, which also says that sapwood is less dense, due to its role as a transport hub for water to the crown. In construction, it is believed that this part will deteriorate and wear out faster due to fungal rot or mechanical stress. Pine sapwood in summer period becomes blue-black or green, the same color penetrates to the beginning of the core. This phenomenon occurs due to the influence of staining fungi. These fungi do not spoil absolutely anything in the tree except its appearance, and they feed on substances that are present in the sapwood
How then is it possible for a less stable layer of wood to protect a more durable one?
Now let's go backwards. The most interesting thing is that adherents of this myth of deficiency say that this is precisely the most durable layer. Then timber (profiled and glued), as well as a number of other building materials, are no good at all. In this case, it turns out that all the coverings must be made of logs: frames for doors and windows, sheathing and rafters, and most importantly, work with an ax.
By logical argument, we can say that for rounded logs, the removal of sapwood is not a disadvantage. On the contrary, removing young layers reduces the risk of rotting.
And to finally refute the disadvantages of rounded logs regarding production, imagine that you are the owner of such a production. You have purchased raw materials with a diameter from 220 to 330 mm, about 2500 cubic meters. Fans of hand-cutting say that when removing sapwood, 30 or even 40% of the diameter of the log is removed. Then it turns out that at the output we get OCB with a diameter of 200 - 240 mm, and in cubic capacity we get 1500 cubic meters. The cost of such production of one cubic meter will be 10,000 rubles. As a result, it turns out that production is unprofitable, because the average selling price of rounded logs per cubic meter is 7000-7500 rubles and no one will work at a loss, this is obvious. Traditional processing from 2500 cubic meters. produces 2300 cubic meters. processed material. Due to the fact that the wood is sorted by diameter, only 1-3 cm is removed.
“Disadvantage” No. 2: It’s cold in OCB houses!
This option is possible if you used an OCB with a diameter of 180 mm, the area of the house is 250 m2, and the house itself is heated by one oil heater.
When designing a house for all-season use, you need to consider some parameters:
- The diameter of logs for residential buildings should be from 240 to 320 mm; there is simply no point in taking more.
- The cubic capacity of the house must be taken into account: the more air there is, the more difficult it is to retain heat.
- The floors of the first floor and the roof must be insulated; they account for 17 to 23% of the heat loss of the house.
Wall material such as rounded logs have quite positive reviews. This building material is characterized by good thermal insulation and attractive appearance.
The quality of the material depends on the equipment where it was processed, on the place of growth (for OCB, the further north, the better), and also everything depends on the specialists who participate in the production.
Very important point is correct installation wall kit, you need to correctly install the dowels, lay the inter-crown seal or insulation. All work must be carried out by qualified specialists: from the device roofing pie before calculating shrinkage and caulking of walls. It is also important to use only quality materials and related tools.
“Disadvantage” No. 3: Rounded logs crack and burst
Naturally, any natural material with natural moisture is indeed subject to shrinkage and drying out. And that's okay - it's not plastic. But as the owners of houses made of rounded logs say, reviews and complaints that excessive cracks appear without human intervention are fictitious. Luckily, there are sealants available to seal cracks. wooden walls, by the way, they were invented even earlier than the rounded log. To avoid the appearance of unnecessary cracks you need to:
- after the log house, treat the ends with PVA glue or lime, this promotes uniform release of moisture from the material, which means that the internal stress in the log will be significantly reduced;
- not worth a log possessing high humidity, coat with paintwork materials, which forms a film on the surface of the material;
- Incorrectly turned on heating is the main reason for significant cracking of the log and the formation of negative reviews. After completion of construction it is necessary to obtain detailed instructions about how to properly put a house into operation and follow it.
“Disadvantage” No. 4: The cost of a house from the Central Bank is higher than the cost of a log house
A log house is good appearance can be as beautiful as a log house.
At the same time, the cost of a log house is 25% more expensive than the cost of the same house from the Central Bank.
If the cost is the same, then perhaps you are lucky, but if it is lower, then you risk getting a house in which it will be a shame to receive guests, and you will feel uncomfortable and cold there.
If you don’t believe the words, then you can’t go against the numbers:
- When producing OCB, cutting cups at the factory is free, in any case, any self-respecting factory will not indicate this as a separate item in the price list. So, for cutting one bowl by hand, you will need to pay from 200 to 500 rubles, and a “Canadian” one will cost up to 1,750 rubles for 1 piece. There are approximately 700 to 3000 of them in the house, it all depends on the number of cuts and the height of the house. It turns out that the bowls will cost from 150 thousand to a million rubles, if not more. It takes up to half an hour to make one bowl: the machine cuts one bowl in 10 seconds, but it is impossible to cut out one high-quality one in less than 20 minutes, and this is a big minus in terms of assembly time.
- Cutting a groove takes even more time, and even masters can make mistakes. Only you are not destined to find out about this, the groove is inside. There is less chance that the machine will make a mistake, and you can check the grooves during unloading. In production, running a log into a groove takes 2 minutes, and cutting a groove takes about 30 minutes, this without any additional measurements and fittings, which are impossible to do without.
- A log house needs more serious caulking than a house made from OCB. The average price of caulking on both sides is plus or minus 100 rubles per linear meter. (50-60 rubles per linear meter / 1 side) In an 8x8 house there are approximately 1000 meters of groove, you will have to pay 100,000 rubles only for caulking, which will need to be produced 2 times.
We come to the conclusion that a house from OCB can be cut on a machine in 2-3 days, and the team will do the same work for several months.
The cost of a house made from OCB in comparison with the cost of hand-cutting:
Manual cutting costs about 9,500 rubles per cubic meter with a diameter of 240-280 mm. For an 8x8 house you will need 75 cubic meters of raw materials, in total you will spend 712,500 rubles, plus lumber costs approximately 85,000, delivery and assembly for roofing felt will cost 420,000, other materials for assembly cost a total of 50,000. In general, a good-quality house without jambs will cost a minus RUR 1,250,000, without foundation, but with delivery, accommodation for craftsmen and other related expenses.
The same house, but from OCB, with perfect cups and grooves, will cost about 950,000 rubles.
“Disadvantage” No. 5: Grandfathers knew what they were doing, and progress and development of technology is bad
At the same time, I would like to ask the question why hewers use machines and not horses. Getting to the heart of the matter, it is the development of technology that now allows us to build more durable houses. The first OCB houses were built 70 years ago, and to this day they look no worse. Perhaps even better than chopped ones due to their perfectly even shapes.
Finally:
To summarize, I would like to voice information that is not directly mentioned anywhere.
Producers of securities are large companies with huge capital. For example, the cost of the entire technological line for the production of proper quality central bank with a diameter of up to 300 mm is $450,000. It is these companies that buy huge volumes of first-grade logs, logs without rungs, this is necessary so as not to break machines, but the remains with bent logs and defects are increasingly going to small companies and enterprises. They also create all sorts of reviews and myths for gullible customers.
This is not an attempt to make arguments for anyone, we simply encourage logical reasoning. Perhaps the authors of reviews and myths about rounded logs simply cannot afford the costs of a production line.
In turn, the owners of the central bank production never denied the obvious:
- a house made of laminated veneer lumber is superior to a house made of OCB in all respects except price, which is the main disadvantage of the technology;
- brick house stronger than any wooden house;
- frame house may be warmer and even cheaper;
- a log house is a certain sign of prestige; a real log house is very expensive.
Any material has its pros and cons and is worthy of certain reviews. All technologies are good in their own way. We produce and build houses from rounded logs and do it as well as possible, because... We have high-quality equipment, sufficient experience and undeniable professionalism of our assembly teams. To produce OCB, we use only northern forest, which is distinguished by its excellent characteristics, warmth and durability. During our work, clients leave only positive reviews about houses made of rounded logs!
Many people dream of building their own house and forgetting about living in apartments. They believe that living in a house is much better, because you have a plot nearby where you can grow anything or, in some cases, have an animal farm. There are so many materials in the world from which one can start building a house, but mainly in their dreams many people imagine log house. In which the aroma of wood will be present, and the appearance of such a house will be pleasing to the eye.
Nowadays you can read a lot of information on various forums. Some of the owners of these write positive reviews, while others, on the contrary, are upset about the construction wooden house. Why is this happening? It’s simple, when such a house was being built, perhaps some rules were violated during construction or poor-quality material was chosen.
In our article we will look at the pros and cons of a rounded house and reviews from the owners. To make it easier for you to make your choice - whether to build such a house or make it from a different type of material.
To form your opinion about a log house and whether it is comfortable to live in it, you can, of course, listen to the opinions of people already living in these houses. But it is worth remembering that each person is built differently, so opinions on this matter will be subjective. Therefore, the primary task for the formation own opinion you need to find out all the advantages and disadvantages of this building material from experts.
The advantages of a rounded house are as follows.
Beautiful appearance. This advantage has a direct connection with the manufacturing technology of such logs. During cylindering, the bark is completely removed from the logs, and the products are made of the same correct shape.
Fast and easy assembly of a rounded house. Regular logs They are processed during construction, after which, for tight joining, each log is adjusted to fit the other. This takes a lot of time.
Price rounded logs for a house is acceptable. Such a house will cost you more money than construction from other materials (or). Why are savings happening? Wooden structures lighter than the others, therefore a lightweight base is made for them, and also an optional internal and external finishing, because such a house looks beautiful without it.
The tree is natural material so it's environmentally friendly pure material. It creates a beneficial microclimate in the house, and thanks to the smells of pine, therapeutic and preventive actions can also be carried out.
The tree is low, because of this summer time it is not hot in such a room, but in winter it is warm in a wooden house.
IMPORTANT! The logs fit tightly together, but to create another layer of protection from drafts and moisture, you need to use. We have discussed all the main advantages, let’s move on to the disadvantages. Because every building material has them.
Disadvantages of rounded logs
Based on the reviews of people living in them, as well as the opinions of experts, such a house has the following disadvantages:
A house made of rounded logs undergoes shrinkage, which can reach up to 10% and take a long period of time. During which it will not be possible to move into the house and install it (this takes about 6-12 months). If you do not adhere to this rule, damage to the roof and finishing may occur.
In order for shrinkage to last for 3 months, you need to build a house from logs that have been chamber dried.
It also happens that shrinkage occurs as you live in the house. Because of this, windows and doors are immediately installed in casings designed for this purpose. To prevent them from breaking during shrinkage.
During the process of making rounded logs, a protective resin layer is also removed along with the bark, which prevents the influence of moisture and the influence of insects. Therefore, to give logs this protective function again, they are treated with special chemicals.
IMPORTANT! Chemical treatment with protective agents is carried out regularly every 3 years. Based on all these pros and cons, we can conclude that a rounded log is still good material for building a house, bathhouse, etc. The main thing is to choose quality material.
Negative reviews from owners that were made erroneously
Let's consider bad reviews owners, which are caused precisely by the purchase of low-quality wood.
- — It’s cold in a house made of rounded logs. The main thing here is to correctly install the wall kit and lay the insulation. Therefore, it is important to entrust such work to truly professional workers. And also purchase only high-quality lumber.
IMPORTANT! The quality of the tree will largely depend on the equipment in which it was processed, and on the place where the tree grew. For example, the further north it grew, the better quality it will be.
- — rounded logs often crack. The appearance of cracks can be avoided, the main thing is to adhere to the following rules: treat the ends of the logs with PVA glue or lime, which will help moisture get out of the wood; It is better not to coat logs with paint; After completion of construction, you need to be instructed by specialists on the rules for putting the house into operation. If the heating is turned on incorrectly, the logs will begin to crack.
- These are often negative reviews, as we see, if you follow the rules when building a house from rounded logs, as well as choosing materials, you can avoid all this. On the Internet you can see many training videos about this.
Positive feedback from the owners of such houses
- “I have been living in the house since 2016, I can say with confidence that it is warm and comfortable, the walls of the houses breathe, the smell of wood has a beneficial effect on the general condition, and in hot summers the inside of the house is fresh.”
- “A house made of rounded logs looks very beautiful, standing out from many brick and other houses, living in such a house you get a feeling of its reliability and strength, the main thing is to wait for the time for shrinkage”
This is just a small part of the positive reviews from satisfied owners. In this article, we have fully revealed all the advantages of building a house from this particular material, and indicated what disadvantages it has. Now the choice is yours.
